l IMPROVEMENT IN MACHINES FOR CASTING MEDALS.

Specification forming part of Letters-Patent No. [82,589, datedSeptember 26, 1876 application filed February 16, 1876.

To all whom it may concern Be it known that I, WILLIAM B. MOORE, of thecity and county of Camden, and State of New Jersey, have invented a newand useful Improvement in Machines for Casting Medals, Goins, Toys,Suc.; and I do hereby declare the following to be a clear and exactdescription of the nature thereof, sufficient to enable others skilledin the art to which my invention appertains to fully understand, make,and use the same, reference being had to the accompanying drawings,making partof this specilication, in which- Figure 1isa side view of thedevice enr bodying my invention. Fi-g. 2 is a front view thereof. Fig. 3is a top view of a portion thereof. Fig. 4.- is a horizontal section ofa portion in line .e m, Fig. 2. Fig. 5 is a face view of one ofthe dies.

Similar letters of reference indicate corresponding parts in the severalgures.

My invention consists in means for readily closing and opening thematrix, whereby the article will be cast and discharged. It alsoconsists in rendering the matrix adjustable relatively to the thicknessof articles to be cast.

Referring to the drawings, A represents a furnace, and B the pumpthereof, which parts are mounted on a support, (l, and operate in amanner similar to that in machines for casting type and other articles.D represents a frame, which is hinged to the support G, and receives anoscillating motion to and from the discharge side ofthe furnace by meansof a cam, a, on the main shaft b, or otherwise.

To the oscillating frame D there is hinged a lever, E, which receivesswinging motion in a direction transverse to the frame D through themedium of a cam, c, on the shaft b, or other appliance. F represents acarrier for one portion or side, G, of the die. This carrier is fittedto, and guided in, the upper end of the frame D, and receivesreciprocating motion from the lever E, pivoted thereto. To the carrierthere is secured one end of a transversely-extending yoke, H, whoseother end is attached to the outer end of the other portion or side, G',of the die, which is fitted to, and guided in, the flap d at the upperend of the frame D, and receives reciprocating motions by means of theyoke H, at-

tached to the carrier F, which is operated by the lever E.

It will be seen that when the two parts of the die move toward eachother to full extent, a space or matrix, e, will be left in the ila'p d,between the working-faces of the die, as seen in Fig. 4, and in saidmatrix the casting will be accomplished.

When the dies are in position, or closed, then, at the proper time, theframe D moves toward the furnace, so that a quantity of molten metal mayenter the matrix e, the dies being securely held. The frame now movesaway from the furnace, the carrier F draws the die G from the Hap d,and, owing to the yoke H, the die G will be forced through the matrix e,toward the die G, whereby the cast article will be discharged. Then theframe advances, the carrier moves the die G toward the Hap, the yokecarries back the die Gso as to leave the matrix open or clear, and afresh quantity of metal flows into the latter, so as to cast anotherarticle, and the discharge thereof and subsequent casting and dischargewill continue as long as desired, the operations being rapidly performedby simple means.

.It will be seen that both dies are simultaneously operated, so as toclose the matrix, and in opening the matrix the cast article will bedischarged by one of the dies.

In order to regulate the depth of the matrix relatively to the thicknessof articles to be cast, the connection of the die G and yoke H consistsof a screw or screw and nut, or both, as atf, so that the said die Gwill have a longer or shorter throw, and thus the space ormatrix will bemade shallower or deeper, the article cast being thereby ofcorresponding depth.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The dies Gr G', connected by the yoke H, and operating substantiallyas and for the purpose set forth.

2. The adjustable connection f of the die G and yoke H, substantially asand for the purpose set forth.A
